A method and apparatus for disrupting material at a tissue site is described. A contact layer may be selected for use on the tissue site and positioned adjacent to the tissue site. The contact layer may include walls defining a plurality of through-holes. A sealing member may be positioned over the contact layer and sealed to tissue surrounding the tissue site to form a sealed space enclosing the contact layer. A negative-pressure source may be fluidly coupled to the sealed space. The negative-pressure source may supply negative pressure to the sealed space and the contact layer to draw tissue into the through-holes to form nodules. The negative pressure may be vented from the sealed space to release the nodules.

The holes have a perforation shape factor and a strut angle causing the plurality of holes to collapse in a direction substantially perpendicular to the opening. The contracting layer generates a closing force substantially parallel to the surface of the tissue site to close the opening in response to application of the negative pressure.

A dressing for treating tissue may be a composite of dressing layers, including a contact layer, a manifold layer, and an adhesive drape. The manifold layer may include one or more layers of felted open-cell foam in some examples. The manifold layer may be relatively thin to reduce the dressing profile and increase flexibility, which can enable it to conform to difficult geometry and other tissue sites under negative pressure. The dressing may have a length and a width less than the length. The manifold layer may include a population of holes extending at least partially therethrough, wherein the holes may be configured to promote anisotropic contraction of the dressing parallel to its width. The population of holes may have a circular, ovoid, triangular, square, hexagonal, irregular, or morphous shape. The dressing may be a bolster that may anisotropically contract to provide a closing force to a linear wound.

Dressing design incorporating formed 3D textile for the delivery of therapeutic negative pressure and compressive forces to a treatment site

A selectively transparent wound therapy dressing, system, and method of use are provided. The dressing may include conformable foam and drape layers, wherein the drape layer has a refractive index substantially within a range of a disclosing liquid. When the disclosing liquid is applied to the drape layer, the drape layer may switch from opaque to transparent. Subsequent evaporation of the disclosing liquid may return the drape layer to an opaque state. Some embodiments provide for paired use with a negative pressure source input device. The method of use provides selective visibility of a treatment site, and reduces the amount of time in which a patient views an acute or traumatic wound or injury.

Wound dressing with selective and dynamic transparency

Sealing members and methods of manufacturing the same are described. A first film layer and a second film layer each having a first side and a second side can be provided. A first adhesive can be coupled to the second side of the first film layer to form a first adhesive layer. A second adhesive can be coupled to the second side of the second film layer to form a second adhesive layer, and a third adhesive can be coupled to the first side of the second film layer to form a third adhesive layer. One or more perforations can be formed through the third adhesive layer, the second film layer, and the second adhesive layer. A first side of the third adhesive layer can be coupled to a second side of the first adhesive layer.

Hybrid silicone and acrylic adhesive cover for use with wound treatment

A dressing or wound filler comprising a laminate structure of materials. In one example embodiment, a dressing may include a first layer comprising a first film, a second layer adjacent to the first layer and comprising a foam, and a third layer comprising a second film. The first layer and the second layer may further include a plurality of perforations or fenestrations. The third layer may include a plurality of raised features. The perforations or fenestrations of the first and second layers may be positioned or aligned with the raised features of the third layer so as to facilitate tearing of the dressing for sizing and application purposes. In some embodiments, the first layer may comprise a polyurethane film, the second layer may comprise a polyurethane foam, and the third layer may comprise an additional polyurethane film.

Tearable dressing structure

An apparatus for filling a wound can include an array of at least four truncated ellipsoids interconnected to define at least one fluid path through, for example perpendicular to, the array.
